2,4-Dinitrophenol may damage the liver and kidneys.
IDENTIFICATION
2,4-Dinitrophenol is a yellow crystalline (sand-like) solid but is often found in a solution. It is used in dyes, photo developers, explosives, and as a preservative of lumber.
REASON FOR CITATION
2,4-Dinitrophenol is on the Hazardous Substance List because it is cited by EPA and DOT.
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910.20.
If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you.

WORKPLACE CONTROLS AND PRACTICES
Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible.
In addition, the following control are recommended:
Where possible, automatically transfer 2,4-Dinitrophenol from drums or other storage containers to process containers.
Before entering a confined space where 2,4-Dinitrophenol may be present, check to make sure that an explosive concentration does not exist.
Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended:
Workers whose clothing has been contaminated by 2,4- Dinitrophenol should change into posure.

PERSONAL PROTECTIVE EQUIPMENT
WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT. However, for some jobs (such as outside work, confined space entry, jobs done only once in a while, or jobs done while workplace controls are being installed), personal protective equipment may be appropriate.
The following recommendations are only guidelines and may not apply to every situation.
Avoid skin contact with 2,4-Dinitrophenol. Wear protective gloves and clothing. Safety equipment suppliers/manufacturers can provide recommendations on the most protective glove/clothing material for your operation.
All protective clothing (suites, gloves, footwear, headgear) should be clean, available each day, and put on before work.
Eye Protection
Wear splash-proof chemical goggles and face shield when working with liquid, unless full facepiece respiratory protection is worn.
Wear dust-proof goggles and face shield when working with powders or dust, unless full facepiece respiratory protection is worn.
Respiratory Protection
IMPROPER USE OF RESPIRATORS IS DANGEROUS.
Such equipment should only be used if the employer has a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing and medical exams, as described in OSHA 1910.134.
